Steam for Linux

Issue Report: After Update: Steam opens in new window, doesn't use proper icon

After recently updating the client it now opens up in a new window,meaning that if you run it for example by clicking the pinned launcher in the unity bar(its icon is themed) it will launch as a different application, which doesn't use the icon in your /usr/share/icons folder, and also doesn't have the jumplist, as the jumplist entries are stored in the usual launcher.
